The CAMentityGraphics class provides graphical output for CAMgeometricEntities. The class is derived from CAMgraphicsProcess and so inherits its functionality. The general use of a CAMgeometricEntity instance (attaching drivers, setting graphics layout, labelling, setting scales, etc.) is identical to the use of a CAMgrahicsProcess instance. A CAMentityGraphics object differs from a CAMgraphicsProcess object only by providing a member function draw(…) which accepts elements of type CAMgeometricEntity or CAMcombinedEntity. The following class diagram depicts the class relationships:
